Why Choose Diamond

Our Story

Dick Suderman, a commercial pilot, and aerial applicator began building custom bi-fold doors in the offseason in the mid 80’s. With a little ingenuity and fabrication skills, Dick was able to meet the unmet bi-fold door needs of local Southern Manitoba shops and aviation hangars.
By 1992, the demand for more doors prompted Dick to start manufacturing on a full-time basis. In 1998, Diamond Doors began operation as a full-scale manufacturing facility. With the help of his sons, the family-run business has steadily grown to be an innovative industry leader in the bi-fold door market.
